IUCN status: Critically Endangered

EPBC Predator Threat Rating: Very high

Studies not in support

No studies

Is the threat claim evidence-based?

There are no studies linking cats to pygmy possum populations.

Evidence linking Burramys parvus to cats. Systematic review of evidence for an association between Burramys parvus and cats. Positive studies are in support of the hypothesis that cats contribute to the decline of Burramys parvus, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance.
